Discover 2 new blood groups

Currently, the four most common blood groups are A, B, AB and O, but scientists have recently discovered two new blood groups, namely Langereis and Junior, a study in Nature Genetics reported.

Experts at the University of Vermont, USA, said the study opened up a lot of hope in the field of medicine such as blood transfusions, body parts replacement, fetal development and coping with radicals. cancer.

This research has opened up a lot of hope in the field of medicine.

'More than 50,000 Japanese people are thought to be Junior negative and may have problems with blood transfusions because of mismatch between mothers and their babies,' said Bryan Ballif, a professor of biology.

He and his colleagues were impressed by the two types of red blood cells called ABCB6 and ABCG2 of red blood cells related to these lesser known blood groups. In the past, we identified 30 proteins that play a role in the formation of a basic blood group but the current number is 32.

Two new blood groups found in a year are great because the latest discovery on this issue has been more than a decade ago.

'Although the antigens of the Junior and Langereis blood groups have been found several decades ago, the genetic basis of these antigens has not been known until now. Research results show that many people have Langereis or Junior blood groups in negative or positive forms but they do not know , "Professor Ballif concluded.
